How Tewkesbury’s storyline in the third film could have been improved.
On one hand, Tewkesbury’s renunciation of his title and departure from the House of Lords effectively undo the events of the first film. His own grandmother had tried to kill him just to prevent him from supporting liberal reform — and now, it turns out, her wish has been partially fulfilled.
On the other hand, however, the situation is far more complex. First of all, the Representation of the People Act of 1884—the very act in question — did not grant the right to vote to the entire population; 40% of men and all women were left out. Secondly—and most importantly — the third film deals with British colonialism, an issue toward which the aristocracy is "somewhat" more favorably disposed.
Perhaps the film should have emphasized this aspect — increasing Tewkesbury’s screen time and giving him a fully developed story arc. Here is how it might look: early in the film, the viscount raises the issue of the mistreatment of the indigenous population in the House of Lords but finds no understanding among his "colleagues." This incident compounds Enola’s anxieties about her future as an aristocrat’s wife and, in turn, fuels doubts in Tewkesbury himself. And in the end, the viscount discovers that his own father—whom the first film portrayed as a liberal and a reformer, and whom he respected and looked up to — had facilitated the theft of gold from Afghanistan.
Another of the perpetrators is a close friend — and the Viscount’s own godfather. It is also worth noting that, although the criminals were arrested, the sentence handed down was surprisingly lenient (thanks to Brigadier Sampson’s connections and social standing). This proves to be the final straw. Tewkesbury realizes that the English aristocracy has reached a moral dead end and that he will achieve nothing more in the House of Lords; the other lords remain too deeply entrenched in conservatism to support his initiatives. You must admit, in that case, renouncing the title and leaving the House would have looked different. I would also like to add that leaving the House of Lords does not equate to a final exit from politics. Ernest could run for a seat in the House of Commons. Its influence grew significantly towards the end of the 19th century, and by 1910, it would take center stage. The franchise’s creators could well portray Ernest as one of the "architects" of this shift—or even as a close associate of Prime Minister Asquith (though that is still twenty years away, there is no telling what timeframe the franchise might cover).
I’m not sure the creators will go down that path. There is a risk that Ernest might overshadow the main character — his current wife. But surely they won’t turn him into a loafer. There is still a chance to come up with something worthy for him.
